Problems solved by technology

However, the development of hydrogen fuel cell vehicles needs to be matched with a large number of hydrogen refueling stations. The construction cost of hydrogen refueling stations is high, the site requirements are high, and the surrounding environment is also high. As a result, there are defects in the distribution of hydrogen refueling stations, and hydrogen refueling stations cannot be built in some areas. , especially some remote and economically backward areas
Currently, there is no good solution to this problem

Abstract

The invention provides a water electrolysis hydrogen production device and application thereof, and relates to the technical field of electrolysis devices. The device comprises a tank body, a tank body base, electrolysis electrodes and an electrolysis diaphragm, the tank body comprises a shell and separation sheets, and the separation sheets are arranged in the shell and divide the shell into a plurality of independent chambers, the shell is connected with the tank body base in a matched mode, a fastening groove detachable from the partition piece is formed in the tank body base, the electrolysis electrodes are installed on the tank body base, each chamber is internally provided with one electrolysis electrode correspondingly, and the tank body base is provided with power connection contacts matched with the electrolysis electrodes; an electrolytic diaphragm assembly port and an electrolytic diaphragm window are arranged at one end, close to the tank body base, of the separation sheet; the electrolytic diaphragm is inserted into the separation sheet through the electrolytic diaphragm assembly port and is in contact with the electrolyte through the electrolytic diaphragm window; a gas-liquid hole is formed in the top of the tank body, and a gas core is arranged in the gas-liquid hole. The device can be used as an emergency or daily standby gas source, and hydrogen and oxygen can be provided for gas equipment such as a hydrogen fuel cell automobile without depending on a hydrogen refueling station.

Description

technical field [0001] The invention relates to the technical field of electrolysis devices, in particular to a hydrogen production device by electrolysis of water and its application. Background technique [0002] At present, all countries in the world are facing the problems of environmental degradation and energy resource shortage to varying degrees, so it is necessary to vigorously develop clean energy technology and renewable energy technology. [0003] Hydrogen is an extremely clean energy carrier that produces only water and no other emissions during its use, so it has attracted widespread attention. There are many ways to produce hydrogen. Among them, hydrogen production by electrolysis of water is a process that only consumes electricity and water to continuously obtain high-purity hydrogen. This technology can be combined with renewable energy for large-scale and low-cost hydrogen production. The produced hydrogen can be used in power generation, metallurgy, chemi...
